Abstract (en)
[origin: WO2010008696A1] A multilayer film is provided which has a core layer, a matte tie layer, and a sealant skin layer. The matte tie layer is intermediate the core and sealant skin layers and comprises a first polymer component and a second polymer component. The multilayer film has a surface roughness (Ra) of at least 0.25 µm and a peak count (Pc) of at least 30 as measured by surface profilometry, and a seal of the sealant layer to itself has a seal strength of greater than about 1400 g/2.54 cm at 127°C. The multilayer film may be oriented in at least one direction and may be metallized, coated, printed, and/or laminated. The multilayer film may be usefully in packaging applications.
